The invention relates to an incongruent six-propeller helicopter provided with four same fixed-pitch propellers with horizontal rotating surfaces, the connecting lines of the rotating centers of the four fixed-pitch propellers are square or rectangular, and the center of the square or rectangular is located on the gravity center of a helicopter body or slightly behind the gravity center. A centralpropeller with a horizontal rotating surface is arranged above the gravity center of the top of the helicopter body, the rotating center of the central propeller is located on the gravity center of the helicopter body or slightly behind the gravity center, and a tail fixed-pitch propeller with the rotating surface perpendicular to or approximately perpendicular to the rotating surface of the central propeller is arranged at the tail of the helicopter body. An undercarriage is arranged below the helicopter body near the gravity center; The size of the central propeller and the power of an engine for driving the central propeller are the maximum, the central propeller provides most of lift force, the four fixed-pitch propellers with the same horizontal rotating surfaces provide a small partof lift force and are responsible for controlling pitching, rolling and heading, and the tail fixed-pitch propeller cooperatively controls heading, so that the unmanned aerial vehicle has the advantages of long endurance time and high carrying capacity. The incongruent six-propeller helicopter can be applied to transportation, aerial photography, agricultural operation and the like.

    一种不全等六螺旋桨直升机,设置四个相同的旋转面水平的定距螺旋桨,这四个定距螺旋桨的旋转中心的连线是正方形或长方形,该正方形或长方形的中心在机身的重心上或在重心略后,机身顶部重心的上边设置旋转面水平的中心螺旋桨,其旋转中心在机身的重心上或在重心略后,机身尾部设置一个旋转面垂直或近似垂直于中心螺旋桨的旋转面的尾定距螺旋桨,机身下靠近重心附近设置起落架,中心螺旋桨的尺寸和驱动中心螺旋桨的发动机的功率最大,中心螺旋桨提供大部分的升力,四个相同的旋转面水平的定距螺旋桨,提供小部分的升力,并负责操纵俯仰、横滚和航向,尾定距螺旋桨协同操纵航向,具有续航时间长,载重量大的优点,可应用于运输、航拍、农业作业等。
